Description

Disposable one-piece nasobiliary guide

technical field

The utility model relates to an oronasal catheter guiding device, in particular to a disposable integrated nasobiliary duct guiding device, which belongs to the technical field of medical instruments.

Background technique

At present, two methods are mainly adopted in clinical work to carry out mouth-nose conversion. The first method is to insert a disposable sputum suction tube from the nasal cavity into the patient's oral cavity, press the tongue surface with a tongue depressor, and clamp the oropharyngeal end of the sputum suction tube with blood vessel forceps. It is pulled out of the mouth, and one end of the nasobiliary duct is inserted into the cavity of the sputum suction tube, and then the suction tube at the nasal cavity is pulled to pull the nasobiliary duct to the nasal cavity. The main disadvantages are: (1) Pressing the tongue surface with the tongue depressor can easily cause nausea and laryngospasm in the patient; (2) The blood vessel forceps extend into the mouth, and the blood vessel forceps are not disposable items, which increases the chance of cross-infection; (3) The blood vessels extend into the mouth The oral mucosa may be damaged inside; the second method is to bend a section of the macular zebra guide wire into a U-shaped ring and penetrate into the patient's mouth until it reaches the junction between the nasal cavity and the oral cavity, and then insert the suction tube from the nasal cavity to the oral cavity and pass it through. U-shaped ring, pull the guide wire to pull the suction tube out of the mouth smoothly, and pull the nasobiliary duct to the nasal cavity. The main disadvantages are: (1) the insertion of the fingers of the medical staff into the patient's mouth increases the chance of cross-infection, (2) the patient may bite the fingers of the medical staff when the patient is unconscious or nauseated under general anesthesia, (3) with ERCP under general anesthesia For patients under general anesthesia who are obese and have a short neck, the base of the tongue is easy to fall back, and the U-shaped guide wire is very easy to be blocked by the root of the tongue and rebound, so that it cannot reach the appropriate oropharyngeal depth smoothly.

Utility model content

The technical problem to be solved by the utility model is to propose a disposable integrated nasobiliary duct guider for the above shortcomings of the prior art, which can conveniently change the catheter of the digestive tract from the mouth to the nose to prevent cross-infection.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is realized in the following manner: a disposable integrated nasobiliary duct guide is provided, which includes a guide wire, an oropharyngeal catheter, a frame body, and a movable body arranged on the frame body; Push rod, the oropharyngeal catheter is integrated with the frame body, the frame body is provided with a groove for the movable push rod to move back and forth, and the movable push rod is installed in the groove; The guide wire is folded in half into a "U" shape and arranged in the oropharyngeal catheter, and the two ends of the "U"-shaped guide wire are fixedly connected to the movable push rod.

The utility model further defines the technical solution. In the aforementioned disposable integrated nasobiliary duct guide, the front end of the oropharyngeal catheter is arranged in an arc-shaped structure that coincides with the throat, and the cross-section of the outlet end is rectangular or oblong. Ensure that the position of the guide wire is relatively fixed when it extends out of the oropharyngeal catheter, and it is not easy to deflect.

In the aforementioned disposable integrated nasobiliary duct guide, the movable push rod is provided with a locking device connected and fixed to the frame body. When the guide wire reaches the set position, the movable push rod is locked by the locking device to prevent nasal The guide wire moves during the passage of the bile duct, which affects the conversion success rate.

Further, for the aforementioned disposable integrated nasobiliary duct guide, the frame is provided with a scale indicating the position of the movable push rod.

The beneficial effects of the utility model are: (1) the hands of the medical staff are outside the patient's mouth during the whole operation, thereby avoiding cross-infection; (2) the medical staff do not need to extend their fingers into the patient's oral cavity to avoid the patient's teeth being bitten; (3) ) When patients with ERCP under general anesthesia switch from nasobiliary duct to mouth and nose, they can easily avoid the root of the tongue, which greatly improves the success rate of nose-to-mouth conversion.

detailed description

The utility model is described in further detail below:

Example 1

A disposable integrated nasobiliary duct guide provided in this embodiment has a structure as shown in Fig. The front end of the pharyngeal catheter is arranged in an arc-shaped structure that matches the throat, and the cross-section of the outlet end is rectangular; the oropharyngeal catheter is integrated with the frame body, and the frame body is provided with grooves for the movable push rod to move back and forth. The rod is installed in the groove, and the movable push rod is provided with a locking device 5 connected and fixed with the frame body, and a scale indicating the position of the movable push rod is arranged on the frame body; The two ends of the "U"-shaped guide wire are fixedly connected to the movable push rod.

When this embodiment is in use, the nasobiliary duct guide can be inserted into the patient’s oropharynx to smoothly pass over the base of the tongue, push the movable push rod forward, release the U-shaped ring at the front end of the guide wire, and extend the suction tube from the nasal cavity into the oral cavity , pass through the U-shaped ring at the front end of the guide wire, tighten the guide wire through the movable push rod, fix the suction tube and the guide, then pull the nasobiliary duct guide, pull the suction tube into the mouth smoothly, and then pull the nasobiliary duct Insert one end of the suction tube, pull the suction tube at the nasal cavity, and pull the nasobiliary duct into the nasal cavity smoothly, and then complete the conversion of the nasobiliary tube to the mouth and nose.

The utility model improves the success rate of disposable nasobiliary duct mouth-nose conversion from less than 70% to 96.7% under general anesthesia, which greatly reduces the clinical workload, reduces the probability of cross-infection, and prevents patients from biting medical staff unconsciously occurrence of finger events.

The above embodiments are only to illustrate the technical ideas of the utility model, and cannot limit the protection scope of the utility model with this. Any changes made on the basis of the technical solutions according to the technical ideas proposed by the utility model all fall into the scope of the utility model. within the scope of the new protection.
